Implements sameAs to use Rotonde from multiple machines

[cblgh]

As described in #147 sameAs is an extension to portal.json.

It adds an array sameAs that contains entries to other portals. If those portals in turn have your portal in their sameAs arrays, you are considered remotes of each other.

The entire point is to decouple your Rotonde portal from a single machine. Using this feature you can now:

• see the same feed as your remotes
• others following your portal will see the posts you make from remotes
• mentions to either the source portal or its remotes will be visible in the mentions tab

Start using it:

If your main portal is dat://7f2ee...0c5/ and your work computer has a portal at dat://3ba71...829/

1. Visit your main portal at dat://7f2ee...0c5/ and run mirror dat://3ba71...829/
2. Visit your work portal at dat://3ba71...829/ and run mirror dat://7f2ee...0c5/
3. You're done! You can now Rotonde from any of the machines with ease.

Remove remotes using the unmirror command: unmirror dat://7f2ee...0c5/ this severs the link between remotes.

Thanks to @0x0ade for some back and forth across twitter, rotonde and github! :~

Who wants to have the honour of pressing merge?

I'm imagining you two staring with a dead-serious glaze at the screen, cursor over the merge button, finger over the mouse button... 🍿

Just read the high level description, looks like a solid solution.

I got Paul's blessing, I'm merging.
